Leos,

'1in the head and that the travel a comparatlvely short om their point of unison the us described my invention, what ier of the character described, on oi a head and a tip, said .ia sway in' conducting a :tobi tible inici and a combusiiuid to said tip, said head drical chamber with which. id passageway communici.E the axis oi' said chamn `zor carried by the head and e.. conduit for supplying a cmerting huid to said injector, and a conduit discharging tangentially into said chamber and conducting a combustible fluid thereto.

lin a burner of the character described, the combination ot a head Aand a tip, said 'head having a passageway for conducting a mixture ot fluids to said tp and a cylindrical chamber with which the inlet end of said .tageway con'unanicates at one side of the s said chamber, an injector projecting' said chamber in substantially axial ement with the inlet lto said passageway, f nenduit for supplying Huid to said injeo and a conduit discharging tangentially imo said chamber andconducting another i fluid thereto.

13 lin a burner of the character described', c combination of a head and tip, said head mig a passageway adapted to deliver a ture of a combustible and a combustionsupporting fluid to said tip and having a cylindrical chamber with the upper portion whereof the inlet end of said passageway cornoninicates, an injector projecting into said chamber inisubstantially axial alineincnt with such inlet, means for supplying a combustion-supporting fluid to said injector, and a conduit ior a combustible fluid comimuiicating with the lower portion of Said chamber and extending' 'from the side thereof Jfrom which the said injector projects.

l. in. a burner of the character described, con'ibination of a head and a tip, said l d having a passageway for conducting a mii. 1re et fluids to said tip and a chamber hei/ing' an inclined wall and with which chamber the inlet and of said passageway communicates, an injector projecting into .said chamber in substantially axial aline ment with the inlet to said passageway, a ronduit 'for suj'iplying fluid to said injector, and a conduit adapted to discharge another fluid against the inclined wall of said chamber.

il. iin a burner of the character described, the combination of a head and a tip, Said 'nto said chain-ber in substan-.' ahnement with the lnlet to said l ist sa head having a passageway for conductin mixture ot fluids to said tip and a cylin cal chamber with which the inlet end of said plsgelvby COIllmllIllCLtQS, 2LH UJQCOI' PTO ject/ing into said charnlier, conduit for supplying fluid to said injector, and a conduit apted to conduct another duid to said inber and to discharge such tluid against cylindrical wall ot said chamber at Va int spaced from the said passo. lin a burner of the character described, he combination of a head having a chamber and a tip communicating therewith, a chamber in said head at one side ofthe first mentioned chamber, a passageway connecting said chambers, anv injector projecting into the second chamber in substantially axial alinement with the said passageway, a conduit for supplying fluid to said injector, and

a second conduit adapted to discharge anpther fluid into the second chamber and against the wall thereof at a point spaced' from said passageway.

another Huid into the seco d chamber and against an inclined portion of the wall thereof at a point spaced from said assage way whereby a whirling motion will be irriparted to the second fluid by such inclined portion of the chamber wall.

i 8, In a burner of the character described, the combination of a head having a chamber drical chamber in said head at one side of the first mentioned chamber, a passageway connecting the upper portion of the second chamber with the first mentioned chamber, an injector projecting into the second chamber in substantially'axial alinement with the said passageway, a conduit for supplying fluid to said injector', and a. second conduit and a tip communicating therewith, a cylinadapted discharge another duid into said j chamber beneath said injector and against the cylindrical wall of the chamber below said passageway.

9. 'ln avburner, the combination of a head the lower end whereof is externally 'thread ed, a tip adapted to be carried .by said head and tor communicate therewith, a gland nut threaded onto the lower .end ot said head. and having' an inwardly directed shoulder beneath such end and a downwardly directed extension adapted to form an elongated 'bearing with said tip, thereby to conter the same, thesaid extension being' rounded inwardly toward the bottom thereof te provide a ehedding surface for rnolten meta-l or slag, and packing materiel interposed betweenseid shoulder and the lower end of seid head.

10, 'In a burner, the combination of a head the lower end i whereor` is externally threaded, e tip adapted to be carried by said heed and to communicate therewith, and a .glnd nut threaded onto the lower end of lo'feeid head and having a downwardly dirested extension adapted to provide an elongated bearin withv said tip to center the Same, the sei extension being rounded inwardly toward the bottom tliereoito pro vide a shedding surface for molten metal or slag.

InA testimony whereof, I hereunto aix niv signature. i
